## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Undershoot, approach - vfr pattern - final approach
  - proper glidepath - not maintained, dual student (cause)
  - inattentive, pilot in command(cfi) (contributing factor)
  - aborted landing - misjudged, pilot in command(cfi) (contributing factor)
  - raising of flaps - premature, pilot in command(cfi) (cause)
  - airspeed - not maintained, pilot in command(cfi) (cause)
- In flight collision with terrain/water, landing

## Analysis

THE INSTRUCTOR STATED THAT THE STUDENT HAD DONE WELL DURING THIS DUAL SESSION, AND HE FELT THAT TRAFFIC PATTERN AIRWORK WOULD BE APPROPRIATE. TRAFFIC PATTERN ENTRY AND LETDOWN WERE NORMAL, BUT THE STUDENT GOT TOO LOW AND SLOW ON THE FULL FLAP FINAL APPROACH. HE FURTHER STATED THAT AT THIS POINT HE TOOK CONTROL OF THE AIRCRAFT AND TRIED TO ARREST THE DESCENT WHILE MAINTAINING AIRSPEED. WHILE INITIATING A GO-AROUND, HE RETRACTED THE FLAPS AND THE AIRCRAFT LANDED HARD ON THE RUNWAY IN AN UNSTABLE ATTITUDE. THE RIGHT WING CONTACTED THE GROUND FIRST, THEN THE NOSE GEAR WAS SHEARED OFF AS THE AIRPLANE SKIDDED TO A STOP.
